Description Giuseppe Bilotta 2009-01-12 20:34:18 UTC
Between 2.6.27 and 2.6.28 my HP dv5 laptop lost sound output from the integrated speakers. Headphones work correctly.

Bisecting identifies this commit as being the culprit:

I am not sure if this is related to bug 12159, so I'm reporting it separately.
Comment 1 Takashi Iwai 2009-01-13 03:52:12 UTC
Please run alsa-info.sh with --no-upload option, and attach the generated file to here.  The script is found in

Then, try to pass model=hp-m4.  This will set the GPIO.

I'm attaching the alsa-info output for 2.6.28. I'll try the option and see if it fixes the problem.

lscpi output

model=hp-m4 does indeed fix the output from the main speakers. I'm attaching the lspci output for my sound card. If I understand the workings correctly, I can probably cook up a patch to fix the problem

Patch to add the quirk for my system

The attached git patch adds a quirk for my machine.
Comment 5 Takashi Iwai 2009-01-13 06:16:39 UTC
Thanks, applied now to sound git tree.

Could you attach alsa-info output on the working status, too?

alsa-info output from working config

Here it is. This is from v2.6.29-rc1-191-g2db8ebb which is latest upstream from Linus plus the patch I attached here.
Comment 7 Takashi Iwai 2009-01-13 07:02:10 UTC
Thanks.  As mentioned, the patch was already applied.
Will be included in the next pull request.
Comment 8 Giuseppe Bilotta 2009-01-13 14:18:52 UTC
Actually, there seems to be a problem: when the model is set to hp-m4, either manually (using the model= option on the module before the patch) or automatically (patched module), the integrated speakers are enabled but the integrated mic is disabled, so I can listen to sounds but I cannot record or use Skype. So this fix is either wrong or not adequate.

Sorry for the noise, I only tested the sound output.

Reopening the bug. So the problem is currently the following:

* without the patch, and without setting hp-m4 as model, the front mic (integrated) is present, can be selected as input source and it works correctly, but the integrated speakers don't produce any sound, although the headphones work correctly

* with the patch, or by setting the hp-m4 model manually, the speakers produce sound but the integrated mic is not seen anymore and it's not offered as input source; I don't have an external mic to test with
Comment 9 Takashi Iwai 2009-01-13 23:25:53 UTC
OK, what about the patch below?

alsa-info.sh output with the dv5 patch

The patch seems to work correctly (tested on latest git). I'm also attaching the output from alsa-info.sh with this patch applied.
Comment 12 Errico Prota 2009-01-18 08:28:15 UTC
Hi Takashi! I have exacly the same problem of Giuseppe, using a dv4 pavilion series...
I tried your patch for dv5 series without success, internal microphones don't work, instead external mic and speakers work fine for me. I am using 
  "options model=hp-m4  and enable-msi=1"  for the module.
kernel is a vanilla 2.6.28 running in ubuntu 8.10 
I think that a quirk is needed also for dv4 series...
I have added an attachment with alsa-information
Thanks for your attention, Errico

Comment 15 Takashi Iwai 2009-01-21 03:57:48 UTC
With my dv5 patch, pass model=hp-dv5 instead of hp-m4, and reboot once after that to restore the BIOS status.

At best, try sound.git tree below:
    git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git master
You can pull master branch onto Linus git tree.
Comment 16 Errico Prota 2009-01-21 12:11:11 UTC
Hi Takashi, I have tried model=hp-dv5 but without success... The behaviour is the same that model=hp-m4 (internal mic don't works). Thanks, Errico
Comment 17 Takashi Iwai 2009-01-22 00:45:09 UTC
Did you switch "Input Source" mixer between Mic and Line?
Also please give alsa-info output with model=hp-dv5.
Comment 18 Errico Prota 2009-01-22 03:46:02 UTC
Hi Takashi, good news after a little troubleshooting... 

Passing model=hp-dv5 it's possible enable "digital input" source in the mixer settings (I use GNOME panel). 

This is not possible with model=hp-m4 option.

Selecting "digital Mic1" in "digital input" integrated mic now works! 
This is the only setting which works, using digital mic2 I have no voice at all. 

In "input source" (without "digital") is selectable only "mic". 
Now "Line" option is no present passing hp-dv5 option.

BTW, the audio-card is usable only with "enable-msi=1", without this, I have a terrible looping audio (with hp-dv5 or hp-m4).

External mic works allways fine.
I'am attaching alsa-utils output (model=hp-dv5)

alsa-info output with Takashi's path applied and model=hp-dv5 option

Internal mic of dv4 works using "Digital input" source, setting "Digital mic 1"
Comment 20 Takashi Iwai 2009-01-22 04:03:49 UTC
Thanks.  Now I committed the patch to set the proper model (hp-dv5) for your device to sound git tree.  It'll be included in the next pull request.

Let's close the bug now.
Comment 21 Howard Chu 2009-01-29 21:26:21 UTC
Fyi, HP makes two parallel lines of laptops, one with Intel CPU and one with AMD. I have a dv5z (AMD) and the audio is also not working on it with kernel I added model=hp-dv5 to my modprobe options and it works now. The PCI ID is 0x3600, not 0x3603:

+		      "HP dv5", STAC_HP_DV5),
Comment 22 Takashi Iwai 2009-01-30 06:52:09 UTC
The entry is added now to sound git tree.  Thanks.
